Compare any two graphics cards:
GeForce GTS 250 512MB vs Radeon R7 250
IntroThe GeForce GTS 250 512MB features a GPU core clock speed of 738 MHz, and the 512 MB of GDDR3 RAM runs at 1100 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 Texture Address Units, and 16 ROPs.Compare those specifications to the Radeon R7 250, which comes with a clock frequency of 1000 MHz and a GDDR5 memory frequency of 1150 MHz. It also features a 128-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon R7 250 is 5% faster than the GeForce GTS 250 512MB in general, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTS 250 512MB is a lot (more or less 97%) more effective at AF than the Radeon R7 250. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTS 250 512MB is superior to the Radeon R7 250, by far. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
